In Resistance to Gender Quotas in Latin America, Malu A. C. Gatto addresses a significant gap in the literature on mandatory legislative gender quotas. While many studies have examined how male-dominated legislatures have enacted gender quota laws, Gatto advances the debate by shifting the analytical focus to the behavior of the average male legislator. Her book offers a parsimonious and compelling explanation of a central puzzle: why would male legislators, whose power is potentially threatened by quotas, support such measures? Gatto argues that male legislators resist gender quotas through a variety of strategies and only concede support when the political costs of continued resistance outweigh the costs of adoption. Even then, they often attempt to weaken the implementation and impact of the quotas.
Building on established theories of political ambition and the conception of legislators as single-minded seekers of reelection, primarily motivated by career concerns, Gatto contends that male legislators face a Hamletian dilemma: to support or not to support gender quotas. On one hand, electoral candidate slots are limited, and greater inclusion of women necessarily implies the displacement of some men. The stronger the quota, the higher the likelihood that women will be elected and that male incumbents will lose their seats. On the other hand, gender equality has become increasingly associated with democratic legitimacy. Open opposition to quotas, therefore, risks reputational damage among voters and peers. As a result, many male legislators find themselves caught between competing incentives: protecting their careers while avoiding the political cost of appearing regressive.
Gatto’s analysis reveals that the ideal scenario for male legislators is to avoid the implementation of gender quotas altogether while simultaneously avoiding the stigma of public opposition. When this is not feasible, they may publicly endorse quotas to preserve their reputations, while working behind the scenes to dilute or hollow out their effectiveness. This argument not only illuminates the conditions under which quotas are adopted but also sheds light on the often contentious processes and timing surrounding their implementation.
An especially valuable contribution of the book is Gatto’s attention to the heterogeneity among male legislators. She demonstrates that not all men perceive quotas as equally threatening. Male legislators with high political ambition but limited capital, such as those lacking secure electoral bases, are particularly vulnerable. This allows for nuanced theoretical expectations that vary beyond ideology and across both institutional and contextual conditions. For example, even though legislators from the left are significantly more supportive of gender quotas, the level of support drops significantly in men with high legislative ambition. Also, the structure of the electoral system plays a critical role: male legislators elected under open-list proportional representation systems, where personal vote-seeking is favoured, face different strategic calculations than those elected through closed-list systems. In addition, context matters, as broader dynamics, such as party system volatility or electoral reform, may shift the calculus of quota support over time.
These theoretical insights are explored through three carefully selected case studies: Brazil, Costa Rica, and Chile. The selection captures meaningful variation in legislative ambition and vulnerability to displacement. Chilean legislators, for instance, enjoy high reelection rates and operate in a context that rewards personal vote cultivation. In contrast, Costa Rican legislators are term-limited and elected via closed lists, while Brazil occupies an intermediate position. Gatto employs a multi-method approach, drawing on experimental designs, quantitative observational data, archival research, and in-depth interviews. This strengthens the empirical foundation of her argument and underlines the complexity of male legislators’ resistance to quotas.
Qualitative methods, in particular, enable Gatto to unpack the multi-layered and often opaque processes of policy design and implementation. This is where the book makes one of its most significant contributions. Political scientists are acutely aware that policy outcomes are often determined in the fine print. Accordingly, Gatto demonstrates how male legislators shape quota laws in ways that protect their own political careers. She convincingly shows that resistance goes beyond formal opposition. It involves subtle but effective manoeuvres aimed at reducing the impact of quotas on women’s electoral success. A simple analysis of roll-call votes could not have captured the full extent of resistance. Rather, Gatto reveals how male legislators deploy procedural tactics, exploit legal loopholes, engage in strategic framing, and use delaying techniques to weaken the transformative potential of quota laws. The book therefore stands out for accounting not only for the moment of quota adoption but also for the full legislative process, offering a compelling explanation of variation in both the strength and timing of quota laws across cases.
One of the relatively weaker elements of the argument, however, concerns the claim that male legislators are deterred from opposing quotas due to reputational costs. While the association between gender equality and democratic legitimacy is increasingly strong, the empirical evidence supporting the reputational risks of opposing quotas remains less robust. Even in open-list electoral systems, it is often difficult for voters to identify and punish individual candidates who resist gender inclusion. Political parties, rather than specific legislators, are more commonly viewed as either supportive or oppositional to women’s rights. As such, this component of the argument is less compelling than others, though it does not undermine the overall strength of the book’s theoretical contribution.
Gatto effectively shows that the emergence of strong quotas and parity laws in Latin America is not the result of male legislators’ voluntary or enthusiastic commitment to gender equality in political representation. On the contrary, these measures are often adopted despite conspicuous resistance from male legislators. Their eventual enactment, if anything, reflects the persistent and strategic pressure exerted by other forces, such as civil society organisations, alongside the crucial support of key actors within the judiciary and the executive branch.
The pursuit of gender equality in general, and women’s representation in particular, is an ongoing and often challenging process. As Simone de Beauvoir reminds us, the final goal may never be fully achieved, for our rights are never guaranteed, and we must remain vigilant throughout our lives to defend and advance them.
